Jesse Kornbluth reviews a mug you simply cannot pass up.

READER REVIEW:‘I bought one of these last year on your recommendation and I can’t stop telling people what a great buy this is. 6 hours hot? Sometimes I put coffee in at 10 PM and it is still steaming when I open it at my work desk the next day at 8 AM.’

What is astonishing about the Zojirushi is how long hot stays hot and how long cold stays cold. Fill it with 16 ounces of steaming coffee in the morning, and six hours later, you can still burn your lips. Put ice cubes in a cold drink, and, six hours later, there’s still ice.

Stylish? It’s sleek. Fits in a tote. Fits in your car’s cup holder. And in black, it’s what you give to Anna Wintour. (It also comes in gold, red and pink.)
